Scientific Notation Calculator: Instantly Convert Numbers

Dealing with extremely large or small numbers? Our Scientific Notation Calculator makes it quick and easy to convert any number into scientific notation and vice versa. Whether you’re a student working on homework, a scientist analyzing data, or an engineer needing precision, this tool provides accurate and immediate results.

Scientific notation is a method of expressing numbers as a product of a coefficient and a power of 10. For example, the number 650,000 becomes 6.5 × 10⁵, and 0.00042 becomes 4.2 × 10⁻⁴. This makes calculations with extremely large or tiny numbers much more manageable.

With our free online calculator, you can:

• Convert standard numbers to scientific notation
• Convert scientific notation back to decimal form
• Handle both positive and negative exponents
• Save time and reduce human error

This tool is ideal for math and science classes, research papers, lab reports, and everyday problem-solving. No downloads or sign-ups—just fast, accurate results every time.
